' The improved mop includes a stick or handle 10, a head 11, a swab clamp 12, and a swab 13. Fixed on the inner end'of the stick-1'0 is a T-head 14. and formed in said stick is a pair of annular lock-grooves 15 and 16 spaced longitudinally thereof. The head 11 is in the form of asleeve through which the stick 10 extends with freedom for endwise sliding movement and for turning movement about the longitudnal' axis of said stick. Y 5' Applied to the upper end portion of the head 11 is a corrugated hand grip 17 0i rubber or any other suitable material and by which the head 11 is held while sliding the same longitudinally on the stick 10 or while turning the same thereon.

The swab clamp 12 includes a pair of fixed arms 18 and a pair of cooperating relatively movable arms 19. Said fixed arms 18 are integralwith the lower endof the head 11 at diametrically opposite points and extend radially'therefrom in longitudinal alinement.

ing said arms downward and inward upon themselves. The two movable arms 19 are parallel and are formed from a single spring rodfolded upon itself and laterally spaced. The transverse connection between the two arms 19 affords a from each other.

.1, on. the head 11 in opposite directions will cause'the Eyes 20 and 21 are formed in the outer ends of the arms 18 by foldhinged member 22 whiehextends through the eye 20 and hingedly connects saidfarms to. the respective arm 18 for swinging movement toward or from the arms l8. v I

To releasably hold the arms 19 in operative. relation to the clamping arms 18 they are provided at their free ends with lock fingers 23 which exe tend endwise into the eye 21 fromopposite ends thereof. These look fingers 23 are formed by bending-the outer :end portion of the arms l9 lat'erallyinward. To remove thefingers 23 from the eye 21 or insertthe same therein it is only necessary to spring the The spring arms 19 also perform another important function in that they cooperate with either lock-groove 15 or l6.to hold the head 11' on thestick' 1G in predetermined adjustments- The diameter of the stick 10 is such as to hold the arms 19 spread apart when out o-f the grooves 15 and 16 so that when said arms are brought into registration with either onev thereofthey' will snap into therespective. groove and thereby hold .the stick 10 andhead 11 against relative longitudinal movement. A pull on the sti'ck'lG and arms 19 to beycammed outof the lock-groove 15 013.16 with which they are interlocked." The lock-groove 15 is closely positioned 'to the'T-head 14 and the lock-groove 16 is positioned. a distance outward of the T-head liwhich. is substantially arms '19 laterally away f equal to the length of the swab .13, as will p-resently appear. r

The swab 13, as shown, is of the knitted type, is substantially flat and its length is considerably longer than its width. This swab 13 is folded upon itself and provided at the free ends of its twoplies with a hem 24 preferably formed from asingle piece of canvas or other suitable material and secured thereto by stitchesX. The purpose of this hem 24 is to provide simple and efficient meansfor detachably securing the swab 13 to the head .11 by means ofthe clamp 12. It

loo

will benoted that thearms 19 extend longitudinally through the hem Ziand with said hem squeezed between the arms 18 and 19. The stick 10 extends through a hole 25in the hem 24 and anopening 26 between'the free ends of the two.-

plies of the swab. 13, see Fig.6.

'When the swab 13 is used as a 'mop the stick 10 is retracted with respectto the head ll and,

said stick and head held against relatively longitudinal movement by the arms 19 and cooperat ing lock-groove 15. In this position of the head 11 on the stick 1c the T-headl4 is in the opening 26 and by it's engagement with the two-plies of the swab 13 prevents the connected end of .said

of the stick 10. It will thus be seen that the arms 19, cooperating lock-rgroove 15 andthe T- swab from turning about'the longitudinal axis the mop 13.

is brought into engagement with the closed outer In this adjustment of the end of the swab 13. head 11 on the stick 10 the arms. 19 will snap into the lock-groove 16 and hold said stick and head against relative longitudinal movement.-

With the stick 10 thus adjusted with respect to the head 11 the operator grips the stick 10 in one hand and the hand grip 17 in the other and then turns the same in opposite directions, thus twisting the swab 13 about the sticklO which produces a wringing action on the swab 13. During this twisting of the swab 13 about the stick '10 the inner end thereof is held by the clamp 12 to turn with the head 11 and the outer end of said swab isheld by the T-head 14 to turn with the Stick 10.

When wringing the swab 13 the stick 10 and the head 11 are held against relative longitudinal movement by the clamping arms 19 and lockgroove 16, as previousiy stated, which causes the swab 13 to stretch and thereby assist in wringing Obviously, the annular lock-groove 16 permits the arms 19 to turn therein during wringing action "of the swab 13. As .shown, the two plies of the swab 13 are connected at their longitudinal edge portions partway up from the closed outer end of said swab, as indicated at Y, to form a sort'of a sack which prevents edgewise displacement of the swab 13 I on the T- use of the, swab 13 the stick l0 and head 11 have the same relative adjustment as when holding the swab 13 for wringing action, or in other words, the stick 10 is projected with respect to the head 11 to stretch the swab between thehead 11 and the T-head 14. In this adjustment of the stick 10 andhead 11 the swab 13. is held fiat transversely thereof by the clamplz and the T-head 14. When the swab13 is used as'a cluster the stick 10 and head 11 are held against relative longitudinal movement by the clamping arms 19 and the cooperating lock-groove 16. v e

To apply the swab 13 to the head 11 the fingers 23 are first released from the eye 21 and the clamping arms 19 positioned, as shown in'F'ig. 5. Said arms 19 are then inserted endwise through the hem Qeandthe fingers 23 again inserted into the eye 20to hold the arms 19in operative relation with respect to the arms 18 with the hem 24 clamped therebetween. The outerend of the stick 10 is then inserted betweenthe plies of the swab 13, at one edge of said swab, through the opening 26, the hole 25, and the head '11. This endwise movement of the stick 10 is con- 'tinued until the arms 19 snap into the lock-groove 15 and at which time the T-head 14 is positioned From the above description it is evident that the improved mop may be very quickly adjustedfor use as a mop or as a cluster or operated to wring water from the swab.
